Description

A kind of rail vehicle anticreeper

Technical field

This utility model belongs to the safety device of a kind of rail vehicle, is specifically related to a kind of rail vehicle anticreeper.

Background technology

Existing anticreeper is generally made up of parts such as anti-creep front end, guiding mechanism, deformation energy absorption element and installing plates, needs to extend back certain length from train head Herba Plantaginis end during installation, it is therefore desirable to reserved special space in train. In vehicle collisions, guiding mechanism is drawn back, and power-absorbing generation crumple deformation is thus energy-absorbing.

Existing anticreeper in use has following defects that

1. owing to anticreeper to absorb the kinetic energy of at least 100MPa, causing that the bodily form of anticreeper is relatively big, structure is complicated, is not suitable for being arranged in the space that train is limited.

2. power-absorbing destroys, can only single use, cause waste.

3. collision rift vehicle deceleration is unstable, it is possible to secondary collision occurs.

Chinese patent 201510191433.4 discloses a kind of cutting type rail traffic vehicles anticreeper, mutually cuts formation energy-absorbing function when collision by inner cutter assembly and outer cut assembly. But it remains utilization and destroys material to carry out energy-absorbing, and can only use once, it is impossible to recycling.

Utility model content

For the problems referred to above, this utility model aims to provide a kind of simple and practical, saves interior space, can repeatedly Reusability, the stable rail vehicle anticreeper of vehicle deceleration.

This utility model solves the technical scheme of problem: a kind of rail vehicle anticreeper, including the guide holder being fixed on the car body end carriage of train front end, cavity it is provided with in guide holder, guide holder front end is provided with guide through hole, it is equipped with guide post in this guide through hole, guide post can slide in guide through hole, and guide post two ends are stretched out outside guide through hole;

Guide post is fixedly arranged at the front end with anti-creep tooth plate, and anti-creep tooth plate is provided with anti-climbing tooth; Guide post end is fixed with the piston being positioned at guide holder cavity;

It is filled with compressible medium in guide holder cavity.

In technique scheme, guide holder restricted guidance bar can only axially-movable, it is impossible to move up and down, thus preventing having climbed of vehicle, and the risk of minimizing vehicle rollover.

Further, described guide holder cavity wall is provided with relief valve. The pressure cylinder formed when guide holder cavity constantly strengthens along with pressure, and when exceeding the setting value of relief valve, the medium in pressure cylinder is got rid of from relief valve, maintains pressure cylinder internal pressure, to ensure safety.

Described compressible medium is hydraulic oil or air.

Anti-climbing tooth on described anti-creep tooth plate is 7��10, and the centre-to-centre spacing between anti-climbing tooth is 20��40mm.

It it is matched in clearance between described guide post and guide through hole.

When two trains collide and come into contact with, anti-climbing tooth on the anti-creep tooth plate of two trains engages each other, the pressure of vehicle passes to guide post from anti-creep tooth plate, limits moving up and down of guide post by the guide through hole in guide holder, and support vehicles have not been climbed. It is simultaneously directed to bar rearward movement, the piston compressed media of its end, absorb the part kinetic energy of vehicle, after the pressure in cylinder exceedes rated pressure, relief valve starts pressure release.

Medium in compression cylinder produces a stable counteracting force, it is ensured that vehicle deceleration is steady, it is to avoid secondary collision.

This utility model absorbs the impact capacity of vehicle by the damping characteristic in media collapse process, thus reducing the risk of train collision, reduces the car body damage that collision brings, and protection vehicle superior takes advantage of personal security. It is in particular in:

1. simple and practical, the bodily form is little, and total is arranged on an outer surface for Herba Plantaginis end, it is not necessary to other spaces reserved, has saved interior space, has also eliminated design procedure.

2. anticreeper will not be caused damage in the process of collision energy-absorbing, can repeatedly Reusability.

3. collision rift vehicle deceleration is steady, avoids the generation of secondary collision.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the utility model is described in further detail.

Fig. 1 is this utility model anticreeper structural representation.

In figure: 1-anti-creep tooth plate, 2-guide post, 3-guide holder, 4-cavity, 5-relief valve, 6-car body end carriage, the anti-climbing tooth of 7-, 8-piston.

Detailed description of the invention

As shown in Figure 1, a kind of rail vehicle anticreeper, including the guide holder 3 being fixed on train front end car body end carriage 6, cavity 4 it is provided with in guide holder 3, guide holder 3 front end is provided with guide through hole, the cooperation of this guide through hole internal clearance is equipped with guide post 2, and guide post 2 can slide in guide through hole, and guide post 2 two ends are stretched out outside guide through hole.

Guide post 2 is the square entity structure of aluminium alloy, and its height is more than 100mm, and width, more than 50mm, to ensure enough strength and stiffness, can support the weight of half-section vehicle.

Guide post 2 is fixedly arranged at the front end with the anti-creep tooth plate 1 being extruded from by aluminium alloy extrusions, and anti-creep tooth plate 1 is provided with 7��10 anti-climbing teeth 7, and the centre-to-centre spacing between anti-climbing tooth 7 is 20��40mm.

Guide post 2 end is fixed with the piston 8 being positioned at guide holder cavity 4.

It is filled with hydraulic oil in guide holder cavity 4.

Described guide holder 3 cavity wall is provided with relief valve 5.

When two trains collide and come into contact with, anti-climbing tooth 7 on the anti-creep tooth plate 1 of two trains engages each other, the pressure of vehicle passes to guide post 2 from anti-creep tooth plate 1, limits moving up and down of guide post 2 by the guide through hole in guide holder 3, and support vehicles have not been climbed. It is simultaneously directed to bar 2 rearward movement, piston 8 compressed media of its end, absorb the part kinetic energy of vehicle, after the pressure of cavity 4 exceedes rated pressure, relief valve 5 starts pressure release.

Medium in compaction cavum 4 produces a stable counteracting force, it is ensured that vehicle deceleration is steady, it is to avoid secondary collision.
